-of the invention, such as will enable others skilled it the art towhich it appertains to make l and use the same.

A being also This invention relates jointersfor plows.

The object of the invention is to provide a jointer for plows which willeiiciently cut its way through all kinds of weeds and trash, therebypreventing the same from clogging the plow. v kA further object is toprovide means for attaching the jointer to the plow-beam to permit saidjointer to be adjusted laterally, means provided for raising andlowering the jointer.

AWith these and other objects in view the invention consists of certainnovel features of construction, combination, and arrangement of parts,as will be hereinafter described and claimed.

V In the accompanying drawings, Figure 1 is a side view of a portion ofa plow-beam, showing thev jointer applied thereto. Fig. 2 is a frontelevation of the same, partly in section. Fig. 3 is a verticalcross-sectional view through the beam and the rear end of the upperattaching-plate, showing the clamping device for to improvements insecuring the rear end of the same to the beam.

Fig. 4 is a top plan view of the upper attaching-plate. Fig. 5 is asimilar view of the lower attaching-plate. Fig. 6 is a verticalsectional view through the jointer and its attachingbracket, and Fig. 7is a similar view taken at right angles to Fig. 6.

Referring more particularly to the drawings, 1 denotes the plow-beam, onthe under side of which is secured an upper attachingplate 2. Said plateis provided near its forward end with slots 3, said slots being arrangedon opposite sides of the center of the plate, as shown. Through theslots 3 are in- Serted upwardly-projecting bolts 4, which are adapted toproject on each side of the plowbeam, the upper ends of the boltspassing through a clamping-bar 5, which engages the upper side of theplow-beam. On the upper ends of the bolts 4 are adapted to be screwednuts. 6, whereby the front end of the attaching-plate 2 is rmly clampedto the plow-beam. The rear end of the plate 2 is recessed or cut away,as at 7, and in said cut-away or recessed portion is slidably mounted apair of clampingbars 8, said bars being provided with alinedlongitudinally disposed slots, through which is passed a securing-bolt7', which also passes through an aperture 8 in the end of the plate 2.The outer ends of the clamping-bars 9 are provided withupwardlyprojecting lugs 10, which are roughened on their inner sides andare adapted to engage the opposite sides of the plow-beam. When the lugs10 have been firmly engaged with the sides of the plow-beam, the nut onthe bolt 9 is tightened, thereby holding said clampingbars into tightengagement with the beam, and thus securing the rear end of the plate 2to the beam. The front end of the plate 2 is provided with adownwardly-projecting rightangularly-formed extension 13, in which is Yformed a transverse horizontally-disposed slot 14.

On the lower side of the plate 2 is secured a lower attaching-plate 15,said plate being provided near its rear end with a transverselydisposedslot 16, through which and a centrally-disposed aperture 17, formed inthe plate 2, is inserted a bolt 18. On the lower end of the bolt 18 isscrewed a nut 19, thereby adjustably securing this end of the plate Y k15 to the upper attaching-plate 2. On the forwardV end of the lowerplate 15 is formed a downwardly-projecting right-angularly disposedprojection 20, in which is formed a centrally-disposed aperture 21.Through this aperture 21 and through the slot 14 in the eX- tension 13of the upper plate is passed a bolt 22, on the outer end of which isscrewed a nut, whereby the forward end of the lower plate is adjustablysecured to theupper plate. On the under side of the plate 15 is formed adownwardly-projecting obliquely-disposed arm 23, in one side of which isformed a longitudinally-disposed channel 24. The arm 23 is also providedwith a longitudinally-disposed slot 25. In the channel 24 of the arm 23is adjustably secured the upper end of a jointer-standard 26, saidstandard being provided near its upper end with a bolt-hole, throughwhich and the slot 25 of the arm 23 is arranged a bolt 27. Said bolt isprovided on its end with a nut 28, which when screwed up into engagementwith the side of the arm 23 will securely hold the standard 26 in any ofits adjusted positions on the arm 23, thus IOO IIO

p permitting the jointer to be raised or lowered,

as desired. On the lower end of the standard 26 is formed an enlargement28, said enlargement being provided with a verticallydisposed aperture29, the lower side of the enlargement 28 being provided with a roughenedor serrated surface.

Adapted to be engaged with and secured to the enlargement 28 of thestandard 26 is a bearing-bracket 30, said bracket being provided with aright-angularly formed arm, the upper side of which is provided with aroughened surface which is adapted to engage the roughened surface ofthe enlargement 28. The right-angularly-formed arm of the bracket 30 isalso provided with a vertically-disposed aperture 31, which is adaptedto aline with the aperture 29 in the enlargement 28, and through saidalined apertures is passed a securing-bolt 32, on the lower end of whichis adapted to be screwed a nut 33, which when screwed upon the bolt 32will securely clamp the bracket 30 to the enlargement 28. In thevertical arm of the bracket 30 is formed a transverselydisposed aperture33', in which is adapted to be inserted a bearing-box 34. In the box 34is mounted a short shaft or spindle 35, between which and the box 34 isdisposed a bushing 36. On the shaft or spindle 35, adjacent to the outerend of the same, is rigidly secured a circular plate 37, to which isbolted or otherwise secured a disk jointer 38. Said disk is providedwith a centrally-disposed aperture 39 to iit over the end of the shaftor spindle, the outer end of said shaft or spindle being provided withscrew-threads, on which is adapted to be screwed a nut 40, by which thedisk jointer is rigidly held on the spindle 35. The disk jointer is hereshown as secured to the plate 37 by means of screw-bolts 41, which arecountersunk in the disk 38. On the opposite end of the spindle 35 isscrewed a securing-nut 42, whereby the shaft or spindle 35 is secured inthe bracket. rlhe box 34 is secured in the aperture 33 of thebearingbracket by means of a set-screw 43.

A jointer constructed and arranged as herein shown and described may beadjusted laterally on the plow-beam and may be also lengthened orshortened, the construction of the parts also being' such as to permitthe jointer to be arranged on either side ofthe standard, as will beunderstood. j

While the device is shown as being connected with a wooden-beam plow, itis obvious that the same may be connected or applied to a steel or ironbeam without materially chang'- ing the construction of any of theparts.

From the foregoing` description, taken in connection with theaccompanying drawings, the construction and operation of the inventionwill bc readily understood without requiring a more extendedexplanation.

Various changes in the form, proportion, and the minor details ofconstruction may be resorted to without departing from the principle orsacrificing any of the advantages of this invention. a A

l. A jointer of the character described comprising upper and lowerattaching-plates, means for clamping said upper plate to the plow-beam,means whereby said plates are connected together to permit them to beadjusted laterally, a depending arm arranged on said lower plate, ajointer-standard adjustably secured to said arm, and a disk jointerdetachably connected to the lower end of said standard, substantially asdescribed.
